Fill scale — scale_fill • plotit

Maps data values to fill colours. Same semantics as scale_color() but for the fill aesthetic (bars, boxes, polygons, etc.).

Usage

scale_fill(
  plot,
  name = ggplot2::waiver(),
  trans = NULL,
  limits = NULL,
  range = NULL,
  breaks = NULL,
  labels = NULL,
  ...
)

plot: A plotit object.
name: Scale title (legend name). ggplot2::waiver() = use variable name.
trans: Scale transformation. NULL auto-detects, otherwise one of: "identity", "discrete", "reverse", "binned". Unsupported values (e.g. "log") produce a targeted error message.
limits: Data domain.
range: Output range. Same as scale_color(): colour vector, or "viridis", "brewer", "grey", "hue".
breaks: Legend key positions.
labels: Legend key labels.
...: Passed to the underlying ggplot2 scale function.

A modified plotit object.
